Description

This 915MHz omnidirectional antenna is engineered for reliable performance in LoRaWAN, ISM-band telemetry, and 4G/LTE router applications. Its quarter-wave design and 50-ohm impedance ensure efficient RF matching with minimal VSWR loss, maximizing transmitter output power and receiver sensitivity for extended wireless range.

The antenna features a flexible, ruggedized shaft and a fully weatherized construction, making it suitable for outdoor IoT deployments, industrial sensor networks, and embedded systems exposed to harsh environments. The right-angle RP-SMA connector facilitates clean integration into compact enclosures and simplifies cable routing for Raspberry Pi-based gateways, MikroTik routers, and Sierra Wireless cellular modules.

Key Features

  • 915MHz ISM Band Optimized – Precisely tuned for LoRa, Sigfox, and other sub-1GHz wireless protocols common in North American IoT deployments.
  • Low VSWR & High Efficiency – Typical VSWR ≤1.9 at the center frequency ensures minimal reflected power and maximum radiated output.
  • Omnidirectional Radiation Pattern – Delivers uniform 360-degree horizontal coverage ideal for star-topology sensor networks and mobile applications.
  • Robust Mechanical Design – Flexible main shaft resists breakage from bending or impact, while the weatherized housing protects against moisture and dust.
  • RP-SMA Male Connector – Industry-standard reverse-polarity SMA interface compatible with a wide range of wireless modules and development boards.
  • Wide Operating Temperature – Rated from -20°C to +85°C for reliable performance in both extreme cold and hot outdoor installations.

Applications

  • LoRa/LoRaWAN Sensor Nodes & Gateways – Extend range for 915MHz LoRa modules in agricultural, environmental, and asset tracking networks.
  • 4G/LTE Router & Cellular Gateway Upgrades – Replace stock antennas on MikroTik, Sierra Wireless, or custom LTE routers for improved signal strength.
  • Raspberry Pi Wireless Projects – Enhance the range of LoRa HATs or compatible sub-1GHz transceivers on Raspberry Pi Zero W or Pi 4 setups.
  • Industrial IoT & Telemetry – Provide reliable omnidirectional coverage for SCADA, remote monitoring, and M2M communication in the 915MHz ISM band.
  • Embedded Wireless Systems – Integrate into compact enclosures for custom wireless sensors, beacons, and mesh network devices.

Frequently Asked Questions

Is this 915MHz antenna compatible with my LoRa module that has an SMA female port?

This antenna uses an RP-SMA male connector. To connect it to a standard SMA female port, you will need an RP-SMA female to SMA male adapter. Always verify the polarity of your device's connector, as mismatched SMA/RP-SMA connections can cause poor electrical contact and signal loss. Ensure the adapter is rated for 50-ohm impedance and frequencies up to 1 GHz for optimal LoRa performance.

What is the effective range improvement when using this antenna on a LoRa node?

Range improvement depends on your transmitter power, receiver sensitivity, and environment. A 2.2dBi gain provides a modest boost in effective radiated power (ERP) compared to a 0dBi reference. In open areas with a 20dBm LoRa module, you might see a 10-20% increase in reliable communication distance. For maximum range, ensure a clear line of sight, minimal VSWR by using a quality cable, and orient the antenna vertically for proper polarization matching with other nodes.

Can this antenna be used outdoors permanently?

Yes, the antenna is fully weatherized and rated for an operating temperature range of -20°C to +85°C, making it suitable for permanent outdoor installation. For best longevity, ensure the RP-SMA connection is properly sealed against moisture ingress using a waterproof tape or silicone sealant. The flexible shaft is resistant to wind and vibration, but avoid placing it under constant mechanical stress or in direct paths where it could be physically damaged.
